Turbine engine rotor lock

Abstract

A turbine engine rotor lock, in particular for a turbojet fan, adapted to retain a blade axially relative to a disk of the rotor, the lock including a composite body including a woven fiber structure embedded in a matrix; and a damper pad made of elastomer and fastened to the composite body.

The invention claimed is: 
     
       1. A turbine engine rotor comprising:
 a disk; 
 blades attached to the disk; 
 a lock for the turbine engine rotor, the lock retaining at least one of the blades axially relative to the disk of the turbine engine rotor, the lock including: 
 a composite body comprising a woven fiber structure embedded in a matrix, and 
 a damper pad made of elastomer and fastened to the composite body, 
 wherein the woven fiber structure comprises warp yarns and weft yarns oriented such that when the lock is in position on the turbine engine rotor, the warp yarns are oriented in a tangential direction of the turbine engine rotor and the weft yarns are oriented in a radial direction of the turbine engine rotor, or vice versa, 
 wherein each blade is fastened in a slot of the disk by a blade root, 
 wherein the lock is fastened to an axial end of the slot for said at least one of the blades, and 
 wherein the damper pad is situated between the blade root of said at least one of the blades and the composite body. 
 
     
     
       2. The turbine engine rotor according to  claim 1 , wherein the woven fiber structure is made by three-dimensional weaving. 
     
     
       3. The turbine engine rotor according to  claim 1 , wherein a portion of the woven fiber structure, situated opposite the damper pad, forms a projecting tab oriented away from the damper pad. 
     
     
       4. The turbine engine rotor according to  claim 1 , wherein the matrix of the composite body is organic. 
     
     
       5. The turbine engine rotor according to  claim 1 , wherein the damper pad is fastened to the composite body by adhesive bonding.
